How to use
A full swap, start to finish. No account, no wallet connection, no JavaScript — you paste an address and send one deposit.
1Quote
- pick pair
- on /swap choose amount and the two coins, hit Quote. We ask every live line and show the best output on top, the rest as alternatives.
- read it
- the big number is what you receive after all fees — our 0.50% margin is already inside it. Protocol total and the min-in are printed under it. Every protocol quote is protected: it carries an on-chain minimum, and anything below it the protocol refunds instead of executing.
- changed the pair?
- there is no JavaScript here, so numbers don't recalculate as you click — after changing coins or amount, hit ↻ get new quote and the same page reloads with fresh protocol answers. One request, nothing tracking your keystrokes.
2Pick a route
- best vs alt
- the top line wins on output. Want a different one? Click any alternative — the page re-quotes on that line and marks it your pick.
- quiet lines
- a line that can't serve the pair right now is listed as quiet with the reason. That's protocol state, not an error on your end.
3Deposit
- paste address
- enter the address that receives the output. We checksum-validate it before creating the swap — a typo is caught here, not after you send.
- chainflip refund
- on Chainflip you also give a refund address on the source chain — the protocol returns funds there if the swap can't execute (fill-or-kill).
- old addresses die
- After a new quote or a new swap, every earlier deposit address is void. Protocol vaults rotate; a deposit sent to yesterday's address can be unrecoverable. Send only to the address on your current /s/ page.
- minimums
- each line has a minimum per swap — below it the deposit can be eaten by network fees. Live minimums for every coin we carry: /assets; your exact min-in is printed on every quote.
- send once
- you get a deposit address and, on THORChain/Maya, a memo. Send the exact amount with the exact memo, once. The address is valid for a short window shown on the page — never reuse an old one.
4Track & verify
- track
- your swap page is
/s/SP-XXXXX. Find it any time on /track by reference, deposit txid or deposit address. Keep the reference. - receipt
- each swap ships a PGP-signed receipt tied to our signing key. Check it against the key on /verify — the fingerprint there matches the one that signed your receipt.
Memos — read before you send
On THORChain and Maya the memo is the swap: destination, limits and our route live in that one string. Chainflip, Relay and the XMR partner gate don't use memos — their deposit address alone carries the intent.
Refunds return to the sender.On UTXO chains the refund goes to the first input address — never send from an exchange or shared wallet, and don't use HD wallets that move change to a new address.
Memo rules on memo routes (THORChain · Maya)
- when it's required
- every deposit on a THORChain or Maya route. Your /s/ page prints the exact string next to the deposit address — paste it byte-exact, an edited memo can send funds elsewhere
- btc · bch · ltc · doge · dash
- attach as an OP_RETURN output in the deposit transaction — 80-byte limit on these chains. Most exchange withdrawals and many mobile wallets cannot do this
- eth & erc-20 · avax · bnb
- the memo travels in the transaction data of the protocol router deposit call
- atom · xrp · rune · cacao
- the native memo field of the transaction (XRP: Payment type only)
- skipped or broken memo
- the protocol automatically refunds an invalid deposit to the sending address, minus the source-chain fee (fact: dev docs, verified 2026-07-19). Worse cases: memo over 250 bytes or an amount at/below the dust threshold — the network ignores such transactions entirely
- wallet can't attach a memo?
- Do not send. Use a wallet with memo / OP_RETURN support, or pick a route that needs none (Chainflip, Relay, XMR gate)
Lost or wrong? Wrong memo or a deposit after the window can be unrecoverable — quote again rather than reusing an address. Stuck swap with a valid deposit → /contact with your SP-reference.
